I'm lookin into getting the Castle Mamba Monster 2 esc and motor in my Traxxas Summit and was wondering if the Turnigy nano-tech 6000mah 6S 25~50C Lipo Pack will be good to run it w/o issues or burning up the esc and battery. Any advice would be greatly appreciated

Probably destroy the summit drive train before you'd get a chance to burn out the esc. From what I've seen off the Summit trans I'd say it's not designed for anywhere near that sort of power, at least not without extensive hop ups\modding.

isn't the drivetrain identical to the revo? plus the gearbox? so if you swapped out the gearbox it should be ok i would think.

the differentials are also different, and all they are meant to handle is brushed, so you will not want to run them locked, or i have heard they will break down.
